Kev txwv tsis pub ncua ntev polymorphism ( RFLP ) tsom xam yog ib qho ntawm thawj forensic txoj kev siv los soj ntsuam DNA. RFLP tsom xam xav kom cov neeg soj ntsuam kom yaj DNA nyob rau hauv ib qho enzyme uas lov cov strand ntawm tej ntsiab lus. Tus naj npawb ntawm rov ua dua cuam tshuam qhov ntev ntawm txhua qhov tshwm sim ntawm DNA.

Ib yam li ntawd, RFLP siv li cas hauv kev tshawb nrhiav forensic?

Qee qhov kev siv rau RFLP Kev tshuaj ntsuam xyuas muaj xws li: DNA Fingerprinting: Forensic cov kws tshawb fawb tuaj yeem siv RFLP tsom xam los txheeb xyuas cov neeg raug tsim txom raws li cov qauv pov thawj uas tau sau rau ntawm qhov chaw ua txhaum cai. Leej Txiv: RFLP kuj yog siv nyob rau hauv kev txiav txim ntawm leej txiv los yog rau tracing caj ces caj ces.

Ib yam li ntawd, RFLP siv li cas hauv DNA ntiv tes? Vim DNA yog tshwj xeeb rau tus kheej, peb tuaj yeem siv DNA ntiv tes kom phim cov ntaub ntawv caj ces nrog tus neeg nws tuaj. Cov txheej txheem txwv fragment length polymorphism ( RFLP ) "txiav" tawm cov noob uas muaj feem yuav yog qhov sib txawv ntawm cov enzymes txwv.

Hais txog qhov no, RFLP yog dab tsi thiab nws siv li cas?

Txwv tsis pub tawg ntev polymorphisms, los yog RFLPs , yog qhov sib txawv ntawm cov tib neeg nyob rau hauv qhov ntev ntawm DNA fragments txiav los ntawm enzymes. RFLP kev tsom xam tuaj yeem yog siv raws li ib daim ntawv ntawm kev tshuaj ntsuam genetic los soj ntsuam seb ib tug neeg muaj ib tug mutant noob rau ib tug kab mob uas khiav hauv nws tsev neeg.

Dab tsi enzyme yog siv hauv RFLP txheej txheem?

Hauv RFLPs cov DNA yog txiav siv ib qho kev txwv enzyme, ib qho enzyme uas txiav cov DNA tsuas yog qhov twg nws paub txog ib ntu ntawm nucleotides (ib qhov chaw txwv). Cov khoom sib txawv raws li qhov chaw ntawm qhov chaw txwv.
